unity传参数给iOS

1.修改导出的unity工程

与Unity约定交互方式 OnUnityMessage 是约定好的

// UnityMessageListener.m

// Unity-iPhone

// Created by kpl on 2025/7/5.

import<foundation foundation.h=""></foundation>

extern "C" {

void OnUnityMessage(const char* meaasge);

}

=============利用通知把unity消息给原生

// UnityMessageListener.mm

// UnityFramework

// Created by kpl on 2025/7/5.

import<foundation foundation.h=""></foundation>

extern "C" {

extern void OnUnityMessage(const char *objName){

    NSString *msgInfo = [NSString stringWithUTF8String:objName];

   NSDictionary *msgInfoDic = @{@"message": msgInfo};

   [[NSNotificationCenter defaultCenter] postNotificationName:@"OnUnityMessage" object:nil userInfo:msgInfoDic];

   NSLog(@"接收从Unity传递过来的字符串 %@==", msgInfo);

}

}

修改BuildPhase 把.h文件暴露出来

重新编译成Framework

如下图所示

成功后，在把Framework集成到项目中去

在需要地方注册通知，就能获取unity返回的消息了
